Be it known that I, Joan B. LownnY, a

citizen of the United States, residing at San.

Pedro, in th county; of LosAngeles and State of California, haveinvented new and useful Improvements in Hose Clamps, of

i which the following is a specification; I 1

This invention relates toimprovementsfin hose clamps, and has for its object to. pro

vide novel means for clamping a rubber hose orthe like to any desired connecting me dium such as a metallic nipple,

It is an object of this invention topro; vide a clamp for this purpose wherein a positive tie is provided betweenthehose and the connecting medium, thereby producing an efficient clamping action and preventing the possibility of the part s'working aparnl It is a further object of the inventionto' provide a clamp which will beofsiinp le and durable construction, and Wl'llCh.Wlll-;lQQ;TQl-; atively-inexpensive tom anuiacture, 1

Further. objects of the invention will be: come apparent from the following description .ofthe accompanying drawings; in whichr 1 Figure 1 is a longitudinalsection through a hose and a connecting medium, to which it is secured. myimprovedclagmp being ,cmployed thereon I I Figure 2 is a sideelevation.ofthe same.

Figure 3 is a transverse, section talier 1 -on the line 3 .-3 of Fig. 1."

Figure 4 is a detail viewpot one of the-.

tying wires employed, in my improved clamp.

Figure 5 is a view similar'to Fig. 1 of a modified form of my invention.

Figure 6 is a view similar to Fig; 2 of this modification.

Figure 7 is a view similar to Fig. 1 of a still further modification of my invention.

Figure 8 is a transverse section taken on the line 88 of Fig. 7.

Referring to the form of my invention illustrated in Figs. 1 to 1, the end of a section of hose is shown at 1 received over the end of a metallic nipple 2. This nipple may be any well-known or preferred connecting medium to which a nozzle, faucet or the like may be attached in any well-known manner.

For the purpose of illustration I have shown Specification of Letters 1atent- 15:, A nqati fi ea m n,15,,120; Serial Nb, 355929. 5 i W H '1 i The endof the nippleover-which the hose 11s recelved 1s preferably tapered so. that a wedg ng'engagement 1s provided-when'the end of the hose is forced-onto the 'endof then pple, This tapered surface of thenipple. isalso preferablyjspirally grooved gas Shown at 1 0 n r e the gripping actionof the hose upon theinipple. rThexendof-the n ppl 2 w ch p ojects beyon the d the hose 1, is tapered. away; from thehos'e and towardits threaded end-as shown at 7 An annular collar 8; isreoeived; Over this i tapered end of th znipple and is arranged to befirmly wedged upon thenipple. in close P m Y t0 t e'end: of the hose 1.

A tying medium is provided betweeni being drawn togetherfii-n' lany well know-n manner 'asflby; abolt 1O for'Lcl-ampingtthe hose to {the nipple. The tying. mediurn em.

- ployed betweencollar 8and clamping, band 9..Inay-cons1st ofiiwires 11 preferablyarrangedatdiametrically oppositehpoints or';

the coupling. 5 Each of these wiriesar'e shown as U,-shapeId withits arms extending through adjacent apertures 12-; provided in collar '8', and the base ofthefUafQrIned bythe. wire engagingagainstthe collar 8. Thearmsoi wire 11 'are'bent back over collar 8:..and:

alongthe end of hose 1;. and extend Ebeneath clamping-band 9., the ends;.of..:said

of. ithe. wire being f bent back over the clamping band 9. The base of the, U formed by the tying wire is thus positively secured to collar 8 which is in turn firmly wedged upon the nipple 2, and the ends of the tying w1re are firmly secured to the hose 1 by the clamping band. A positive tie is thus provided between the nipple, and the hose which is wedged overthetapered end j of the nipple. y

In the modification illustrated in the Figs- 5 and 6 the hose 1 is received over the tapered end of a nipple 2 the outwardly projecting end of. which consists of an internally threaded cup 3 adapted for threaded engagement with a pipe 4.

Instead of the collar 8 wedged upon the nipple, diametrically disposed longitudinally extending lugs 13 are provided upon nipple 2* adjacent the end of the hose re ceived over said nipple. These lugs are 1 each provided with a transverse aperture In the further modification of my invention as illustrated in Figs. 7 and 8, the hose 1 is received over a nipple 2 which forms a coupling with a pipe 4. This coupling mayconsist of acollar 15 threaded to the end of pipe 4 and provided with an inwardly extending annular shoulder 16 arranged to engage beneath the shoulder formed by an enlarged head 17 provided upon the end of nipplefz In this construction a collar '8' similar to the collar 8 previously described, is received about the nipple 2 adjacent the end of the hose 1. This collar is preferably secured upon the nipple by a threaded engagement 18, the end of the nipple received within the hose being-preferably threaded throughout its length so that the collar may be threaded thereon and properly positioned before the hose is forced overthe'end of the nipple. A clamping band 9 is provided upon the hose and the ends of tying wires secured to the collar 8 are preferably clamped' beneath and bent back upon this clamping band. Instead of the U-"shaped tying wires previously described however, straight wires 11 are preferablyernployed. For this purpose the collar 8 is provided with single apertures '12 at diametrically opposite points and the wires 11 are provided with knotted ends, the wiresfbeing threaded through the apertures until their knotted ends engage co1lar-8 and are then bent back over the collar S and clamped beneath the clamping band 9 as previously described. I i

It will be apparent thatvarious changes in the construction, combination, and arrahgementswf parts h'erein describec l may be resorted to without departing from the spirit and scope of my invention, and I do not wish to limit myself to the exact disclosure herein.

What I claim is:

1. In a hose clamp, a hose, a nipple received within said hose, the projecting end of said nipple being tapered away from said hose, a collar having a wedging engagement upon said tapered end of said nipple, a tie wire threaded through apertures formed in said collar,-and a clamping band for clamping said hose to said nipple, and the ends of which tie wire are formed into hooks which engage said clamping band.

.2. The combination with a hose, of a nipple having a body portion that tapers gradually toward one end, said tapered body portion being positioned in the end of the hose, a' perforated member on said nipple beyond the end of the hose, a clamping. ring encircling that portion of the hose that is positioned on the tapered body portion of the nipple, and a tie wire threaded through the perforated member and having its ends formed into hooks Which engage said clamping ring.

3. A hose clamp comprising a nipple the external surface of which tapers from an i intermediate point toward its ends, one of the tapered portions being longer thanthe other and adapted to be positioned in the end of a hose, a perforated ring removably positioned on the tapered portion of the nipple that projects beyond the end of the hose, a clamping ring encircling the hose and the tapered portion of the nipple that is positioned therein, and tie wires threaded through the perforations in the ring and having their ends formed into books which engage said clamping ring. I

In testimony whereof I have signed my name to this specification.
